Fertigation - feeding crops through the irrigation system - is the backbone of modern intensive farming, and water-soluble fertilizers are the fuel it runs on. This article explains how fully soluble NPK formulas work, why purity and solubility decide success in drip systems, and how to build a season-long program from standard blends.

Soil acidification and structural decline are slow-moving problems that quietly cap yields long before they become visible. Calcium magnesium granules address both at once: calcium flocculates clay into a crumb structure, magnesium feeds the chlorophyll engine, and both nutrients buffer acidity. Here is how the mechanism works and how to build a program around it.

Yellow leaves are one of the most misread symptoms in agriculture — and one of the most costly to misread. When older leaves turn yellow *between* green veins, the cause is usually magnesium deficiency, not nitrogen. This article lists the 10 field signs that give it away, explains how to correct it fast with magnesium sulfate(https://www.rongdafert.com/magnesium-sulfate), and shows how to keep it from coming back next season.

Modern fertilizer programs deliver nitrogen, phosphorus and potassium with precision, yet a fourth nutrient has quietly slipped into deficiency across the world's cropland: sulfur. Cleaner air means less free sulfur deposition, and higher yields mean more sulfur leaves the field in every harvest. This article explains why agricultural ammonium sulfate has become the most practical answer, and how to use it without disturbing your nitrogen balance.

Two growers can apply the same product and get opposite results. The difference is almost never the fertilizer itself — it is the method, the timing and the rate. This guide breaks down base dressing, fertigation and foliar spraying of [**agricultural magnesium sulfate**](https://www.rongdafert.com/magnesium-sulfate) for fruit trees, vegetables and field crops, with practical rates, the logic behind each method, and the four mistakes that waste the most money.

Not every field wants plain urea. Where soils are acidic, compacted or prone to leaching losses, calcium ammonium nitrate delivers nitrogen in a balanced, immediately available form while adding calcium to the root zone. This article explains how CAN works, which fields benefit most, and how to decide between CAN and urea.
